To solve this problem without multiplying the 23 you would have to distribute the 23 to get the answer.

This strategy is also called the distributive property.

You can break the 23 into 8 and 15.
After you did that you have to multiply 8 with 45 and 15 with 45 and then add them together.

If you're not sure about what I'm saying, your work should show this.........

23 x 45 ....... 23= 8+15....... (8x45)+(15x45)

Once you answer the expression you should get 1035

sp2606 [1]

Answer:

$Max = 15$

Step-by-step explanation:

Given

$s(y) = -2y^2 + 60y + 10$

Required

Determine number of items that gives maximum earnings;

The general form of a quadratic equation is:

$s(y) = ay^2 + by + c$

And the maximum is calculated as:

$Max = \frac{-b}{2a}$ If a<0

Comparing $s(y) = ay^2 + by + c$ to $s(y) = -2y^2 + 60y + 10$

We have that:

$a = -2$ $b = 60$ $c = 10$

Substitute these values to

$Max = \frac{-b}{2a}$

$Max = \frac{-60}{2 * -2}$

$Max = \frac{-60}{-4}$

$Max = 15$

<em>The number of item that maximizes the function is when y = 15</em>

h = how many hours he works.

$6 an hour = 6h

t = overtime hours.

$9 an hour for overtime = 9t

m = how much money he made that week.
